LED drive
Control the current behind the pixels
ICND2153 converts serial input data into PWM grayscale output for multiplexed LED displays. Sixteen constant-current channels share an external current-setting resistor. The listed material uses SSOP packaging, so check the AP pinout rather than using the QFN diagrams.
Key functions
Driver functions with defined conditions
Set the output current and scan scheme to match the LED circuit.
02 / scan
1–32 scan support
The device supports time-multiplexed drive for 1–32 scan applications. Serial input data is converted into pixel grayscale through the 16-bit shift register.
03 / correction
Integrated display corrections
LED open detection and pre-charge circuitry address open-LED effects and ghosting, with additional low-gray enhancement.
04 / current matching
Keep channel current consistent
Channel-to-channel and chip-to-chip current error is specified at ±1.0% typical and ±2.0% maximum for consistent output current.
Circuit integration
Match the package and drive signals
Use the AP pinout for the SSOP part. Connect the serial data, clocks, latch/command input, current-setting resistor and constant-current outputs as specified in the datasheet.

Veelgestelde vragen
Frequently asked questions
Which package applies to this material?
The original material record specifies SSOP. In the Chipone datasheet this corresponds to ICND2153AP / SSOP24. QFN24 variants have different pinouts; check the package before replacement.
Does every supply voltage support 25 mA per channel?
No. The datasheet lists 0.5–25 mA at 5 V, 0.5–18 mA at 4.2 V and 0.5–10 mA at 3.3 V. Use the range and circuit conditions appropriate to the actual supply.
What scan modes are supported?
The device supports 1–32 scan time multiplexing. This describes the driver capability and does not by itself specify the resolution or refresh performance of a complete display.
Which control and data signals must the PCB provide?
The documented interface includes SIN serial data, DCLK data clock, LE command input, GCLK PWM clock, SDO serial output and 16 constant-current outputs.
Which datasheet is available for design review?
The current download is the English ICND2153 Driver Datasheet, revision 1.4 dated July 2020. Use its AP/SSOP24 pinout and package drawing for the PCB footprint.
